LIQUID-DISPENSING DEVICE.

Be it known that we, FREonRIoK and GEORGE E. RUssnLL, citizens of the United States, residing at Wilmington, in the county of Los Angeles and State of California, have invented new and useful Improvements in Liquid-Dispensln Devices, of which the. following is a speci eatlon.

Our invention relates to liquid dispensing devices and consists of the novel features herein shown, described and clalmed.

Primarily, our object is to provide a device for automobile service stations for dis-- pensing gasolene, distillate and. the like.

Figure 1 is a fragmentary perspectlveof an automobileservice station provided with a liquid dispensing device in accordance with the principles of our invention. I

Fig. 2 is a fragmentary sectional elevation of the essential parts of the dispensing devlce.

Fig. 3 is a horizontal fragmentary sectional detail on the line 33 of Fig. 2.

Fig. 4 is an enlarged fragmentary elevation of the graduated gage as seen lookmg in the direction indicated by the arrow 4 in Fi 2.

Referring to Fig. 1, the motor 1 operates the air compressor 2, and the air compressor is connected to the air storage tank 3, and the air storage tank is connected by a pipe 4 and branches 5, 6 and 7 are connected to theoil tanks 8, 9 and 10. The oil tanks 8, 9 and 10 may contain gasolene, distillate, engine oil or the like, and the oil tanks are mounted below the pavement 11 and have filling caps 12, 13 and 14 accessible through the pavement for filling the tanks. The stand 15 extends upwardly from the pavement 11, and the pipes 16, 17 and 18 lead from the bottoms of the tanks 8, 9 and 10 to the dispensing valves 19, 20 and 21.

Referring to Figs. 2, 3 and 4, the measuring tank 22 is mounted above the stand and is controlled by a valve 26 convenient to the handles of the valves 19, 20 and 21. The details of the measuring tank 22 are as follows:

The cylindrical casing 27 has a flange 28 resting upon' the rim 29 and secured in place by bolts or rivets30. The rim 29 is formed of the upper flat plate 31 and the lower concavo-convex plate 32. The inlet passage leading from the coupling 25 is formed through a tube 33 extending through the centers of the plates 32 and 31, there being a chamber 34 between the plates 32 and 31 around the tube 33.

The outlet nipple 35 leads from the chamber 34 through the plate 32 downwardly and outwardly and the hose 36 is connected to the nipple 35 and has a nozzle and valve 37 upon its outer end. Valve casings 38, 39,40,41 and 42 extend upwardly from the plate 31 and communicate with the chamber 34, the upper intake ends of the valve casings being graduated in height, and said valve casings being in the measuring chamber 43 above the plate 31 within the casing 27. The top of the casing 27 is closed by a head 44.

- The valves 45, 46, 47, 48 and 49 fit the upper ends of the valve casings 38, 39, 40, 41 and 42 and the valve stems 50 extend from the valves 45, 46, 47, 48 and 49 downwardly through the valve casings 38, 39, 40, 41 and 42 and through the chamber 34 and through stuffin boxes 51 extending downwardly from the plate 32 and have springs 52 upon their lower ends against the stufling boxes and heads 53 upon their lower ends against the springs, so that a desired one of the valves may be opened by pushing upwardly upon the proper one of the heads 53.

A displacement plug 54 is screwed through the head 44 and has an arm 55 extending from its outer end intoalinement with an ear 56 and a padlock 57 has a long locking bar 58 adapted to be inserted through the arm and through the car 56 to hold the displacement plug in its adjusted position.

When the casing 27 has been made to the desired size as near as may be, the casing is filled with liquid and the liquid measured and the displacement plug 54 adjusted to enlarge or reduce the size of the chamber 43 to accurately fit the graduations.

An elbow stufiing box 59 is connected through the casing 27 immediately above the bottom plate 31, a glass gage tube 60 is mounted in the stuffing box"59 a stuffing box 61 is fitted upon the upper end of the lass gage tube 60, and an elbow 62 extends from the stu fling box 61 and is connected to an elbow cap 63 screwed upon the nipple 64 extending upwardly from the center of the head 44.

A protecting casing 65 is secured to the casing 27 and extends around the glass tube and has a slot 66 in its outer side through which the tube 60 may be seen. Faces 67 and 68 are formed upon the casing on each side of: the slot 66 and graduations 69 and 70 are placed upon these faces.

The graduations 69 and 7 O, on the casing 64, are arranged to correspond, or check, with'the upper ends, or valve openings, of the val e casings 38-3940--41 and 42. As, for instance, when the casing 27, is made to contain a certain quantity of liquid, the

valve casings are arranged to draw ofi' por tions or fractions of that quantity, the

proper valve is opened and the result ob- I served in the gage tube 60. As an illustration, assuming the casing 27 to have a capacity of five gallons, and the valve casoff. However, it,is clear that the entire five gallons may be drawn off merely by opening the valve45, and in a like manner intermediate quantities may be drawn off. Any

desired number of valve casings and valves may be provided, but this is not necessary for small quantities as these can be measured on the gage glass 60, in connection with the valves.

A float valve 71 is loosely mounted in the nipple 64. A needle valve 72 extends upwardly from the float 71 to fit the vent hole 73 in the elbow cap 63, so that when the chamber 43 is filled with liquid the float 71 will rise and close the opening 73, and so that when the liquid passes downwardly the float 71 will fall and open the vent 73.

The measuring tank 22 is on a level high enough so that the liquid will run downwardly out of the chamber 43 through the hose 36 and nozzle 37 to the automobile tank, (not shown).

In the practical operation the desiredjone of the valves 19, 20 or 21 will be opened andthe valve 26 will be manipulated to force the liquid from the desired tankc8, 9 or 10 upwardly through the tube 33 into the chamber 43 and the operator will watch the gage 68 and graduations 69 and 7 U until the desired amount of liquid is in the chamber 43, thenthe valve 19, 20 or 21 will be closed. At this time all the valves, 45, 46, 47, 48 and 49 are closed and the liquid will remain in the chamber 43 until the desired one of the valves 45, 46, 47, 48 or 49 is opened by pushing upwardly on the head 53, then the liquid will run out of the chamber 43, through the hose 36 and nozzle 37 to the automobile tank.

Various other uses andoperations are obvious.

Various changes may be made without departing from the spirit of our invention as claimed.

We claim: In a liquid dispensing device, a hollow supporting member, a plurality of supply pipes extending upwardly therethrough, valves arranged in said supply pipes, a tank arranged above said support, said tank having a secondary bottom to form a separate discharge chamber at .the lower end of the tank, a tubular member connecting the upper ends of the supply pipes with the chamber in the upper portion of the tank, the discharge chamber at the lower end of the tank being provided with an outlet opening, a plurality of discharge tubes seated. in the bottom of the tank and extending upwardly therefrom, the lower ends of which tubes communicate with the discharge chamber at the bottom of the tank, valve stems passing upwardly through the bottom of the tank and through said tubes, valves carried by the upper ends of said stems and normally closing the upper ends of said tubes, and handles on the lower ends of said stems. 4

- In testimony whereof we have signed our names to this specification.
